Microsoft Patch Tuesday - January 2012


Microsoft today released first batch of patches to fix their products security flaws for January 2012. Micorsoft released seven security bulletins addressing eight vulnerabilitis in Windows. Vulnerabilities in Windows Media rated as Critical severity. The remaining rated as Important.

Summary of Microsof of January releases can be found at http://technet.microsoft.com/en-us/security/bulletin/ms12-jan

  • MS12-001: Vulnerability in Windows Kernel Could Allow Security Feature Bypass (2644615)

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow an attacker to bypass the SafeSEH security feature in a software application. An attacker could then use other vulnerabilities to leverage the structured exception handler to run arbitrary code. Only software applications that were compiled using Microsoft Visual C++ .NET 2003 can be used to exploit this vulnerability.This patch counter CVE-2012-0001.


  • MS12-002: Vulnerability in Windows Object Packager Could Allow Remote Code Execution (2603381) 

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate file with an embedded packaged object that is located in the same network directory as a specially crafted executable file. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. This patch counter CVE-2012-0009.


  • MS12-003: Vulnerability in Windows Client/Server Run-time Subsystem Could Allow Elevation of Privilege (2646524) 

This security update resolves one privately reported vulnerability in Microsoft Windows. This security update is rated Important for all supported editions of Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008. All supported editions of Windows 7 and Windows Server 2008 R2 are not affected by this vulnerability. This could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application.This patch counter CVE-2012-0005.



  • MS12-004: Vulnerabilities in Windows Media Could Allow Remote Code Execution (2636391)

This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if a user opens a specially crafted media file. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. This patch counter CVE-2012-0003 and CVE-2012-0004.


  •  MS12-005: Vulnerability in Microsoft Windows Could Allow Remote Code Execution (2584146) 

This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Office file containing a malicious embedded ClickOnce application. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. This patch counter CVE-2012-0013.


  •  MS12-006 Vulnerability in SSL/TLS Could Allow Information Disclosure (2643584) 

This security update resolves a publicly disclosed vulnerability in SSL 3.0 and TLS 1.0. This vulnerability affects the protocol itself and is not specific to the Windows operating system. The vulnerability could allow information disclosure if an attacker intercepts encrypted web traffic served from an affected system. TLS 1.1, TLS 1.2, and all cipher suites that do not use CBC mode are not affected. This patch counter CVE-2011-3389.


  •  MS12-007: Vulnerability in AntiXSS Library Could Allow Information Disclosure (2607664) 

This security update resolves one privately reported vulnerability in the Microsoft Anti-Cross Site Scripting (AntiXSS) Library. The vulnerability could allow information disclosure if a an attacker passes a malicious script to a website using the sanitization function of the AntiXSS Library. The consequences of the disclosure of that information depend on the nature of the information itself. Note that this vulnerability would not allow an attacker to execute code or to elevate the attacker’s user rights directly, but it could be used to produce information that could be used to try to further compromise the affected system. Only sites that use the sanitization module of the AntiXSS Library are affected by this vulnerability.This patch counter CVE-2012-0007.

New Yahoo Messenger 0-Day Exploit Hijacks User's Status Update


Malware spread via Yahoo Instant Messenger has been around for years. Infection, though, has been limited by the fact that it requires some interaction with the user.
Not anymore.

A newly discovered exploit in version 11.x of the Messenger client (including the freshly-released 11.5.0.152-us) allows a remote attacker to arbitrarily change the status message of virtually any Yahoo Messenger user that runs the vulnerable version.

How does it work?
The status message change occurs when an attacker simulates sending a file to a user. This action manipulates the $InlineAction parameter (responsible for the way the Messenger form displays the accept or deny the transfer) in order to load an iFrame which, when loaded, swaps the status message for the attacker's custom text. This status may also include a dubious link. This iFrame is sent as a regular message and comes from another Yahoo Instant Messenger user, even if the user is not in the victim’s contact list.

Apache HTTP Server Reverse Proxy - CVE-2011-4317

Engineer from Qualys Security Labs discovered vulnerability in Apache HTTP Server Reverse Proxy/Rewrite URL Validation during creating vulnerability signature for CVE-2011-3368.

The weakness is caused due to the mod_proxy module, when configured in reverse proxy mode, incorrectly processing certain web requests. This can be exploited to send requests to an unintended server behind the proxy via a specially crafted URL.

Full Details with PoC
https://community.qualys.com/blogs/securitylabs/2011/11/23/apache-reverse-proxy-bypass-issue

WorkAround:

Apache has not yet released a patch for this issue. Until a patch is release, configuring the reverse proxy rules correctly will prevent this issue from occurring. For example, in the above case, if the reverse proxy rules are configured as follows, the proof of concept will not work.

RewriteRule ^(.*) http://10.40.2.159/$1
ProxyPassMatch ^(.*) http://10.40.2.159/$1
